The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
A cell type is a classification used to identify cells that share morphological or phenotypical features. [1] A multicellular organism may contain cells of a number of widely differing and specialized cell types, such as muscle cells and skin cells, that differ both in appearance and function yet have identical genomic sequences.
Antonio Peña Díaz (born in 1936) is a Mexican biochemist who received the Carlos J. Finlay Prize for Microbiology (UNESCO, 2003) [1] and chaired both the Mexican Academy of Sciences (1992–93) [3] and the Mexican Society of Biochemistry (1981–83).
Cell most often refers to: . Cell (biology), the functional basic unit of life Cellphone, a phone connected to a cellular network; Clandestine cell, a penetration-resistant form of a secret or outlawed organization
In 1951, Henrietta Lacks was admitted to the Johns Hopkins Hospital with symptoms of irregular vaginal bleeding; she was subsequently treated for cervical cancer. [9] Her first treatment was performed by Lawrence Wharton Jr., who at that time collected tissue samples from her cervix without her consent. [10]
Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles [1] and excluding the nucleus in eukaryotic cells.
The cell cycle.Many tumor suppressors work to regulate the cycle at specific checkpoints in order to prevent damaged cells from replicating. A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. [1]
